nick w, I well understand where you are coming from when you typed of the 912 rusting away in a few months... The first Porsche I owned in the seventies was a rusted out 69 912, which I inexpertly nailed back together, over a period of about a year, making use of two sheets of 6x4` to make up patches to weld in, however despite the corrosion of the monocoque every nut bolt and screw was either plated or made of high quality materials, thus unlike my old brit cars everything electrical and mechanical came apart with comparative ease, suggesting it had been designed and built by engineers as opposed to being under the control of bean counters....
On the negative side, other than body corrosion, at the time as best I can remember, a pair of valve springs (2 per valve) was circa £50, whereas a whole set for my MGB could be had for £14
Julian, my 912 was a 2 litre, I think later models might have been 1.6 as they seem to be in the US.. Once I had it up and running, I could not wait to get my hands on a 911 to see how much more performant it might be....
A couple of pics of it during repairs and once completed..
